Countless unordered textured sandblasted surfaces are generated on the roll surface. This type of textured roll, with a rough, uniform, and high-hardness surface, can be directly used for rolling and tempering cold-rolled thin sheets (strips). It increases rolling speed, improves sheet shape, reduces surface scratches, and helps prevent adhesion during coil annealing. Textured sheets (thickness 0.05–1.2mm) offer excellent elongation and formability, superior paint gloss, and strong chemical coating adhesion, making them ideal materials for automobiles, home appliances, electronic devices, and decorative panels.Main Technical Parameters
